The one he's been working on, one that deals with complications, such as automatic winding, calendar, chronograph. It's been listed as Level 4, and it remains still in development. I will sign up as soon as it's released. I hope, it will not be the last one...
Quick update on this, the lens wasnt glued at all. Just bezel set I to the case like a cabochon stone... I'm assuming that means it's never been replaced.
Anyway, removing it took about 30 seconds. I have the new lug made and ready to solder on (just need to get everyone out of the house for a while so I can work in secret).
I was also able to straighten the bent crown. Things are coming together nicely. I just wish I had more time to work on it!
